SceneSwitcher

An automated scene switcher for OBS Studio

More information can be found on https://obsproject.com/forum/resources/automatic-scene-switching.395/

Compiling in tree

Add the "SceneSwitcher" source directory to your obs-studio source directory under obs-studio/UI/frontend-plugins/:

cd obs-studio/UI/frontend-plugins/
git clone https://github.com/WarmUpTill/SceneSwitcher.git

Then modify the obs-studio/UI/frontend-plugins/CMakeLists.txt file and add an entry for the scene switcher: add_subdirectory(SceneSwitcher)

Compiling out of tree

Prerequisites

You'll need CMake and a working development environment for OBS Studio installed on your computer. Once you've done that, do the following:

git clone https://github.com/WarmUpTill/SceneSwitcher.git
cd SceneSwitcher
mkdir build && cd build

Windows

In cmake-gui, you'll have to set these CMake variables :

• BUILD_OUT_OF_TREE (bool) : true
• LIBOBS_INCLUDE_DIR (path) : location of the libobs subfolder in the source code of OBS Studio, located at [source_directory]/libobs/.
• LIBOBS_LIB (filepath) : location of the obs.dll file (usually set to C:\Program Files\obs-studio\bin\64bit\obs.dll)

Assuming that you installed Qt via the regular Qt App way:

• Qt5Core_DIR (path) : C:/Qt/5.10.1/msvc2017_64/lib/cmake/Qt5Core

• Qt5Gui_DIR (path): C:/Qt/5.10.1/msvc2017_64/lib/cmake/Qt5Gui

• Qt5Widgets_DIR (path) : C:/Qt/5.10.1/msvc2017_64/lib/cmake/Qt5Widgets

• LIBOBS_FRONTEND_API_LIB (filepath) : location of the libobs-frontend-api.dll file, usually C:/Program Files/obs-studio/bin/64bit/obs-frontend-api.dll (usually in the same place as LIBOBS_LIB)

• LIBOBS_FRONTEND_INCLUDE_DIR (path) : location of the obs-frontend-api subfolder in the source code of OBS Studio, located at [source_directory]/UI/obs-frontend-api.

Just keep hitting configure until all the vars are filled out. Then hit generate.

Linux

Most versions of Linux you can use cmake-gui or the command line.

For the command line:

cmake -DBUILD_OUT_OF_TREE=1 -DLIBOBS_INCLUDE_DIR="<path to the libobs/ sub-folder in obs-studio's source code>"
-DLIBOBS_FRONTEND_INCLUDE_DIR="<path to the UI/obs-frontend-api/ sub-folder in obs-studio's source code>"
-DLIBOBS_FRONTEND_API_LIB="< path to the libobs-frontend-api.so file (usually in the same place as LIBOBS_LIB)>"
-DCMAKE_INSTALL_PREFIX=/usr ..
make -j4
sudo make install

For cmake-gui you'll have to set the following variables:

• BUILD_OUT_OF_TREE (bool) : true
• LIBOBS_INCLUDE_DIR (path) : location of the libobs subfolder in the source code of OBS Studio, located at [source_directory]/libobs/.
• LIBOBS_LIB (filepath) : location of the libobs.so file (usually CMake finds this, but if not it'll usually be in /usr/lib/libobs.so)

Assuming that you installed Qt via your system package manager, it should be found automatically. If not, then usually you'll find it in something like:

• Qt5Core_DIR (path) : /usr/lib64/cmake/Qt5Core

• Qt5Gui_DIR (path): /usr/lib64/cmake/Qt5Gui

• Qt5Widgets_DIR (path) : /usr/lib64/cmake/Qt5Widgets

• LIBOBS_FRONTEND_API_LIB (filepath) : location of the libobs-frontend-api.so file (usually in the same place as LIBOBS_LIB)

• LIBOBS_FRONTEND_INCLUDE_DIR (path) : location of the obs-frontend-api subfolder in the source code of OBS Studio, located at [source_directory]/UI/obs-frontend-api.

Just keep hitting configure until all the vars are filled out. Then hit generate.

Then open a terminal in the build folder and type:

make -j4
sudo make install

NOTE: The Linux version of this plugin is dependent on libXScrnSaver.

OS X

In cmake-gui, you'll have to set these CMake variables :

• BUILD_OUT_OF_TREE (bool) : true
• LIBOBS_INCLUDE_DIR (path) : location of the libobs subfolder in the source code of OBS Studio, located at [source_directory]/libobs/.
• LIBOBS_LIB (filepath) : location of the libobs.0.dylib file (usually in /Applications/OBS.app/Contents/Resources/bin/libobs.0.dylib)

Assuming that you installed Qt via the regular Qt App way:

• Qt5Core_DIR (path) : Usually /Applications/Qt/5.10.1/clang_64/lib/cmake/Qt5Core

• Qt5Widgets_DIR (path) : Usually /Applications/Qt/5.10.1/clang_64/lib/cmake/Qt5Widgets

• Qt5MacExtras_DIR (path) : Usually /Applications/Qt/5.10.1/clang_64/lib/cmake/Qt5MacExtras

• LIBOBS_FRONTEND_API_LIB (filepath) : location of the libobs-frontend-api.0.dylib file (usually in usually in /Applications/OBS.app/Contents/Resources/bin/libobs-frontend-api.0.dylib)

• LIBOBS_FRONTEND_INCLUDE_DIR (path) : location of the obs-frontend-api subfolder in the source code of OBS Studio, located at [source_directory]/UI/obs-frontend-api.

Just keep hitting configure until all the vars are filled out. Then hit generate.

Open xcode (or a terminal, depending on the build type you chose), build and copy the advanced-scene-switcher.so file to /Applications/OBS.app/Contents/PlugIns

Note that you might have to adjust the library search paths using the install_name_tool if you want the plugin to run on machines other than your build machine:

install_name_tool -change @rpath/libobs-frontend-api.dylib @executable_path/../Frameworks/libobs-frontend-api.dylib UI/frontend-plugins/SceneSwitcher/advanced-scene-switcher.so
install_name_tool -change @rpath/libobs.0.dylib @executable_path/../Frameworks/libobs.0.dylib UI/frontend-plugins/SceneSwitcher/advanced-scene-switcher.so
install_name_tool -change /usr/local/opt/qt5/lib/QtWidgets.framework/Versions/5/QtWidgets @executable_path/../Frameworks/QtWidgets.framework/Versions/5/QtWidgets UI/frontend-plugins/SceneSwitcher/advanced-scene-switcher.so
install_name_tool -change /usr/local/opt/qt5/lib/QtGui.framework/Versions/5/QtGui @executable_path/../Frameworks/QtGui.framework/Versions/5/QtGui UI/frontend-plugins/SceneSwitcher/advanced-scene-switcher.so
install_name_tool -change /usr/local/opt/qt5/lib/QtCore.framework/Versions/5/QtCore @executable_path/../Frameworks/QtCore.framework/Versions/5/QtCore UI/frontend-plugins/SceneSwitcher/advanced-scene-switcher.so
